The emery wheel abrasive grinding wheel is used for the device of raceway in the grinding hub assembly
Technical field
The utility model relates to a kind of hub bearing abrasive machining device, specifically adopts the emery wheel abrasive grinding wheel to be used for the device of raceway in the grinding hub assembly.
Background technology
The grinding of domestic most of hub bearings now is respectively the outer raceway face and the inside diameter surface of the outward flange dish of hub bearing to be carried out grinding by repeatedly changing emery wheel, this outer raceway face of wheel grinding hub bearing assembly and the inside diameter surface repeatedly changed, not only make the product sequence of grinding many, dimensional discrepancy is big, the tolerance distribution is big, and it is big repeatedly to locate axiality, the error of perpendicularity that benchmark causes.Product quality can not get guaranteeing, causes inefficiency.
Summary of the invention
The utility model adopts the emery wheel abrasive grinding wheel to be used for the device of raceway in the grinding hub assembly at disadvantages of background technology, has reduced operation, and the product size error is little, and steady quality has improved production efficiency.
The technical solution of the utility model is: the emery wheel abrasive grinding wheel is used for the device of raceway in the grinding hub assembly, mainly by emery wheel abrasive grinding wheel machine body, the emery wheel axle, grinding wheel spindle, emery wheel, emery wheel, motor constitutes, it is characterized in that: the centre bore of emery wheel 1 is fixed on the roller shaft, and the emery wheel axle is located on the emery wheel grinding machine hydraulic pressure planker; Emery wheel 1 periphery is provided with a " grinding face, b " grinding face, c " grinding face and d " grinding face.
A on the emery wheel periphery " grinding face, b " grinding face, c " grinding face and d " grinding face and be installed in the grinding that contacts of abrasive grinding wheel periphery on the axle, make the abrasive grinding wheel periphery form a ' grinding face, b ' grinding face, c ' grinding face and d ' grinding face, abrasive grinding wheel is used for raceway grinding in the hub assembly, processes roller surface a face, b face, c face, d face in the hub assembly.
The beneficial effects of the utility model: adopt with the corresponding emery wheel of hub bearing inner surface hub bearing, each section of inner surface raceway are carried out grinding simultaneously, to the grinding of each section of hub bearing outward flange dish inner surface the time, need not change emery wheel, axiality when having guaranteed the grinding of each section of hub bearing outward flange dish inner surface, solved and repeatedly changed emery wheel and need reorientate benchmark, cause the big problem of the product malalignment and the error of perpendicularity, also reduced the product manufacturing procedure, and the product tolerance is little, dimensionally stable, improve production efficiency simultaneously, reduced production cost.

The specific embodiment:
In the embodiment in figure 1, emery wheel is installed on the emery wheel axle on the lathe, and the emery wheel axle is located on the emery wheel grinding machine hydraulic pressure planker, and emery wheel is installed on the grinding wheel spindle; Emery wheel 1 periphery is provided with a " grinding face, b " grinding face, c " grinding face and d " grinding face; The emery wheel grinding face is used for the abrasive grinding wheel periphery, and abrasive grinding wheel is used for the outer raceway grinding of hub assembly; Abrasive grinding wheel is to the outer grinding-shaping of raceway of hub bearing inner flange.
The longitudinal center of abrasive grinding wheel is provided with axis hole, and the periphery of emery wheel is provided with two flat surface grinding sections, rib face, interior roller surface and two peripheries of wheel grinding section grinding hub bearing inner flange.
The utility model is before carrying out grinding to hub bearing outward flange dish inner surface, use earlier the emery wheel abrasive grinding wheel, the raceway and the outside dimension that need be worked into wheel grinding to inner flange, utilize the abrasive grinding wheel that processes that hub bearing outward flange dish is carried out grinding again, make the product that processes meet the product design requirement fully.
